Specification forming part of Letters PatentNo. 39,053", dated J une 30, 1863.- i

Beit known that I, Huiurrmorrel. Towne, of New York, in the county and State of New bydtciire that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings', making part of this specification, and to the letters of reference marked thereon.

The object of my invention is to furnish a flexible joint for pipes that will permit their bending and expansion and contraction with= and-itconsists in fitting thelordiuary iianges with a supplementary flange or pair oi iianges l quired, and in covering the interior of the joint with a sliding sleeve corresponding in diameter to the diameter ofjthe pipes. In this manner the use of stung-boxes, which require constant care and attention to their packing, may be avoided, and the flow oiA duid through the pipe will be practically uniform throughout mentfof the diametenas in an ordinary bellsame, I will proceed t0 describe its construcf tion and operation with reference to the drawc Figures 1 and 2 are a longitudinal section iron waterpipes made according to my inven- L tion and Figs. 3' and-4 are similar -vews of a dii'erent construction ot' parts, also mad according to my said invention.

The same ietters,indicatelsimilar parts,'"or

partsfperibrming similar functionsin the sev-4 'erelid gares.

Thepipes a "and b of Figs. l and 2 have Acompelratively-thin' plate-iron flanges c" and d,

bolted 'tozthe 'ordinary ilan ges cast upon them,

and are spaced atthe peripheries bythe castiron rlngfegthrough which are passed theirfeom nesting-bolts. The internal sleeve, ffis fitted loosely in recesses at the ends ofthe pipes to preserve the' continuity of their bore', with suiiici'entplay to permit the necessary contractioiiand'expansion and with the iexibll.-

'itygequired, This sleeveinaybepi irorgfcr of india-rubber, cemented or otherwise secured j to the interior of the pipes. p

The pair of pipes' represented in Figs. Bland 4 havebut one plate-iron flange to each joint,

one of the pipes having the large iangfe c andthe sliding sleevefcast upon'it.A Y I do 'not claim the seperate parts I have described, as I amf aware that joints with exible 'bells and anges. have hitherto been made, and also that sleeves have been used on the exteriorof pipes to -make the joints -When flanges have been inadmissible, and I do not wish to be understood as restricting myself to the precise proportions and arrangementof the parts hereins'peciiied, but I prefer the systems of construction 'similar to those which I have described and illustrated.

l claim as my invention and desireto se-- ours by Letters Patentc The combination of the exible flange or limoges. with an internal sleeve, substantially' in .the manner described, andfor. the purpose ls peciied. y
